OPTION 1 - Network Update Method (Recommended)
The Network update is straightforward and the easiest way to update your TV. To use this method, your TV must be connected to the internet (512Kbps or faster). If you have a slower connection speed, use the USB Storage Device method instead.
OPTION 2 - USB Storage Device (USB) Update Method
With this method, use a PC to download the firmware update, transfer the update file to a USB storage device, and then install it from the USB storage device onto your TV. You will need a USB storage device with at least 203 MB of space available and formatted for the FAT32 file system. If you're using a USB device for playback of photos, music, or videos on your TV, the same USB device type should work for this update. If the software update is not successful after following the instructions, you may need to format your USB device to the FAT32 file system, or use a different device.
